Its HEPA filter can capture pollutants as small as .3 microns in size, and the unit itself is powerful enough to cover 360 square feet of space. It is one of the larger models that we included though, so if you’re short on space, you may want to consider a more compact option.

If you’re looking to use your purifier in a large room—up to 540 square feet—this Blueair model and its 3-step filtration system could be a perfect fit.

In addition to its washable fabric pre-filter that captures large particles before they enter the unit, this option also uses an activated coconut carbon filter to trap odors from pets, cooking, and smoking. It's also simple to operate, and uses just a single button to power on, as well as switch between different fan modes.

Although this model is louder than most, its wide coverage and powerful fan could make it worth a little extra noise.

The rechargeable battery makes it even more portable, and the USB-C port allows for a decent amount of flexibility when it needs to be charged up. A single charge will last for up to 2.5 hours on high, although the small size only makes it effective for spaces up to 54 square feet.

This slim footprint, combined with its 32-inch height might pose a tipping hazard if you have small children or rambunctious pets, though, so keep that in mind.
